Answer:

x = 0.6

Step-by-step explanation:

2(x+4)+8x = 14

2x+8+8x = 14

10x+8 = 14

10x = 6

(divide by 10)

x= 0.6

what is the surface area of cone with a diameter of 10 centimeters and a slant height of 12 centimeters round your answer to the
Oduvanchick [21]

The surface area of the cone is 266.9cm^2

Explanation:

The diameter of the cone is 10 cms

Thus, the radius of the cone is given by

r=\frac{d}{2} =\frac{10}{2} =5

The slant height of the cone is 12 cms

The formula for surface area of the cone is given by

$S A=\pi r^{2}+\pi r l$

Substituting the values, we get,

$S A=(3.14)(5)^{2}+(3.14)(5)(12)$

$S A=(3.14)25+(3.14)(60)$

SA=78.5+188.4

SA=266.9cm^2

Thus, The surface area of the cone is 266.9cm^2

Which graph is the result of reflecting f(x) = (8)x across the y-axis and then across the x-axis?
VARVARA [1.3K]
Refrection of a function across the y-axis, changes the sign of x in the function.

Thus, given the function:
f(x)=(8)^x
Refrection of the function across the y-axis will result in the function:
g(x)=(8)^{-x}

Refrecting a function across the x-axis, changes the sign of the function.

Thus, refrecting the function:
g(x)=(8)^{-x}
across the x-axis will result in the function:
h(x)=-(8)^{-x}

The graph of f(x)=(8)^x and h(x)=-(8)^{-x} is attached.
The green curve represents the graph of the function f(x)=(8)^x, while the orange curve represents the graph of the function h(x)=-(8)^{-x}.
